The garden dialog now adds a garden as well as edits one (new.json and
create.json on GardensController), and a GardenPicker button opens it from the
home page. A plant_picker helper replaces the home page's separate plant
links and the plant_button partial. The plant dialog asks when it was
planted (Today, Yesterday, Enter date), using a WhenPicker shared with the
harvest dialog. Members with no garden still get the full-page plant link.
